To @ZZ whom it mayconoern.- shown, having the piston 5, rod G, and oper- Be it known that I, SAMUEL O. JONES, of ating-spring 7. rPhe rod 6 is screw-threaded Stillwater, Vashington county, Minnesota, and provided with a thumb-nut S, whereby have invented certain Improvements in Posiwhen the lubricator-receptacle is emptied the 5 5 tive-Feed Automatic Lubricators, of which piston may be lifted against the tension of its the following is a specifica-tion. spring '7 by screwing down the nut.

In the drawings, let 2 represent the main Mounted loosely on the coreshaft by means shaft, turning in the bearing 3, which is to be of its collar is the arm or lever 31, being lubricated. held upon the shaft by means of the cap 10o '5o A represents the lubricator-receptacle, and having a suitable washer 34 interposed which may be made of the cylinder 4, as between the collar and adjacent ratchet.

This lever is provided with the bolt 35, threaded transversely therethrough and provided on its inner end with the spring-controlled pawl 36, adapted to be brought i n to engagement with either of the ratchets of the series, as desired, the bolt being provided with set-nuts 37, whereby it may be set in adj usted positions. The lever 3l depends and lies normally adjacent or upon the shaft 2 or other part from which it is operated and is provided with the lateral spur 38, adapted to be engaged by a projection or cam 39 upon the shaft in its rotation, so as to swing the lever and operate its connected pawl so as to turn the ratchet one step or more with each revolution of the main shaft.

The lever is normally held against the main shaft by means of the restraining-spring 40 and may be adjusted any desired distance away from the shaft by means of the screw 41, thus causing its pawl to engage a greater or less number of ratchet-teeth in each revolution of the shaft.

As shown in Figs. l and 3, I provide a transverse opening 42 below the measuring-chamber, provided with sights 43, so that the oil dropping through the conduit to the bearing may be seen.

The operation of the device is evident from the foregoing description and the drawings. The lubricator-receptacle being filled and the expelling-pressure being applied to the piston in the ordinary manner and the core standing with its opening in registering position with the outlet port of the lubricator receptacle, the contents of the receptacle are forced into the chamber in the core, driving the piston downward to the bottom of the chamber and filling the same.

The rotating of the shaft operates the pawllever, so as to turn the ratchets step by step, by means of the pawl 3G. The ratchets turn until the spur 29 strikes the lower one of the pins 25 upon the collar 24, and the continued movement of the ratchets rotates the collar and connected measuring-core, by reason of the engagement of spur and pin, until the pin 25 strikes the beveled projection 28. The beveled edge of said projection causes the pin to slide downward in its slot, releasing the spur 29 before the pin itself is released from the projection. The collar and its core then stand still until the ratchets have made a half-revolution to bring the spur 29 into engagement with the opposite pin 25. It will thus be seen that with every alternate halfrevolution of the ratchets the core is carried around a halfrevolution, disengagement then taking place, as aforesaid, between the spur 29 and its engaged pin 25, the ratchet-wheels turning freely during the succeeding halfrevolution, when engagement again takes place. lVhen the core has thus been givena half revolution, its diametric chamber is brought into opposite registering position with the ports in the core, thus permitting the contents of the chamber to descend through the connected tube to the journalbearing and a like amount of the contents of the lubricator-receptacle to be forced in to the opposite end, driving the piston downward. At this point the connection between the ratchet and the collar is tripped, as described, so that the core remains stationary until the' engaging devices have turned upon the shaft through a half-revolution, so as to give time for the filling and emptying of the chamber. It will thus be seen that by adjusting the sizel of the ratchets and the n umher of their teeth, or the number of cams upon the main shaft, or otherwise, the relative speed of rotation of the core-shaft as compared with the main shaft may be adjusted at will, and by regulating the capacity of the chamber or opening in the core any desired amount of lubricant may be delivered.

It is also evident that by this mechanism any kind of lubricant adapted to be used upon such bearings may be efficiently used,whether of the more freelyflowing character or of lubricants which require heavy pressure to be expelled from the receptacle, since the parts may be adjusted so that this pressure both. serves to fill the chamber in the core and also serves to drive the piston to the opposite end, forcing -the contents out into the journalbearing, thus making the feed of the lubricator and the bearin g absolutely positive and automatic and Without possibility of variance or irregularity either in the quantity or periods of feeding.
